I wouldn't think you'd feel an earthquake of this magnitude if you were actually RIDING a coaster whan it hit, due to the vibrating shaking and rumbling already present.
Funny how the mind works. Once I heard it was an earthquake (I was eating lunch at Wendy's and felt my booth shaking) my first thought was for a few friends I have in MD and VA. Second was relief that it was not catastrophic. Third was for the people who were at the parks Robert mentioned, as well as Six Flags in Maryland (how'd you miss that one, Robert?) Fourth was for my OTHER friends in those states..the mechanical ones. I'm planning to hit KD and SF in two weeks for my birthday weekend, and I hope Intimidator 305 and Superman were not injured...they're my #1-2 steel coasters!!!
One thing though -- Intimidator 305 was running with only one car. Thus, the line was really long (well, for that right, and for a wednesday morning).
Got me wondering if the other car had some sort of problem from the earthquake. Of course, it could just be they didn't have the personnel to run two cars; the lines were getting long enough that I would assume they'd be running the 2nd car if they could.
Incidentally, a friend of mine was at the park yesterday too, and told me it was not at all crowded.
And the park was not crowded, just the ride, because at over 2 minutes per train, we had more people coming into the line than riding, so it just kept building up.
In all the other times I've ridden, I've never had to wait more than 3 cars or so except when I waited in the front, where it might be 5 or 6. But Wednesday, by the time we gave up and left the line (after only about 10 minutes, but we had hardly moved and as I said there were still at least 8 groups in front of us), there were easily 10 people in every queue line.
Also, they were calling for single riders to come forward -- that's the first time I can remember them doing so, but obviously they wouldn't bother when there's only a 10-minute max wait anyway.
I wonder when they stopped running two cars. I'm usually on the ride first thing, and as I said they always had two trains running. We were late this time because we were down for processing for our haunt jobs, and didn't make it to the ride until 11am.
